<p>A radiotelephone includes a first unit, second unit and third unit with a camera. A hinge device couples the third unit to the first unit to rotate about an axis with respect to the first unit. The hinge device includes a case, a first rotary member, a linear movable member, a resilient member, a second rotary member and a support member. The case has a stopping wall. The first rotary member rotates about the axis with respect to the case and is coupled to the second unit. The linear movable member moves linearly along the axis by interaction with the first rotary member. The resilient member pushes the linear movable member toward the first rotary member. The second rotary member rotates about the axis with respect to the case and is coupled to the third unit. The second rotary member is pushed toward the wall.</p> |
